LT1617: Micropower Inverting DC/DC Converters in SOT-23 Data Sheet10/2/2009PDF142K
Overview
Features and Benefits
- Low Quiescent Current:
- 20µA in Active Mode
- <1µA in Shutdown Mode
- Operates with VIN as Low as 1V
- Low VCESAT Switch: 250mV at 300mA
- Uses Small Surface Mount Components
- High Output Voltage: Up to –34V
- Tiny 5-Lead SOT-23 Package
Product Details
The LT1617/LT1617-1 are micropower inverting DC/DC converters in a 5-lead SOT-23 package. The LT1617 is designed for higher power systems with a 350mA current limit and an input voltage range of 1.2V to 15V, whereas the LT1617-1 is intended for lower power and single-cell applications with a 100mA current limit and an extended input voltage range of 1V to 15V. Otherwise, the two devices are functionally equivalent. Both devices feature a quiescent current of only 20µA at no load, which further reduces to 0.5µA in shutdown. A current limited, fixed off-time control scheme conserves operating current, resulting in high efficiency over a broad range of load current. The 36V switch allows high voltage outputs up to –34V to be easily generated without the use of costly transformers. The LT1617’s low off-time of 400ns permits the use of tiny, low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.
